    Description

      When an stream server is closed, the close method does not wait until the server keys are canceled with the resources released. This situation can lead to an "Address already in use" error when the same address and port are reused to quickly create a new server.

       

      The server keys are canceled but the close method does not wait until the resources are released.

          Bug - A problem that impairs or prevents the functions of the product. JBEAP-25669 RemotingLegacySubsystemTestCase#testSubsystemWithConnectorPropertyChange intermittently fails

          • Major - To be worked after higher priority work items are addressed. When the severity is high and the effort to change it is low to moderate, this term is chosen. Issues in this category likely have an existing workaround but implementation or execution may be non-trivial.

          Component Upgrade - A task tracking an update to a bundled component or revision of component upstream of the project. WFCORE-6738 CVE-2023-5685 Upgrade XNIO to 3.8.14.Final

          • Blocker - To be worked above all other priorities. This term is chosen when the severity of the issue is very high, has no workaround, or the effort for the change is comparatively low. Issues that may be very publicly visible and could generate significant media attention may also drive a higher priority.
